基于产教融合的高分子化学实验改进探索OA

The synthesis and performance evaluation of styrene-acrylic emulsion represents a classical experiment in polymer chemistry education.Incorporating contemporary industrial applications of styrene-acrylic emulsions into laboratory instruction is a crucial component for achieving effective integration of industry and education.Current teaching materials employ octylphenol polyoxyethylene ether(OP-10)as an emulsifier.In recent years,OP-10 has been restricted by some industries due to environmental concerns.Furthermore,existing curricula are less involved practical applications of these emulsions,limiting the stimulation of students'interest.This experiment implements an industry-aligned approach by utilizing the environmentally friendly reactive emulsifier allyloxy fatty alcohol polyoxyethylene ether ammonium sulfate(SR-10)for emulsion synthesis.We optimized experimental parameters including emulsifier dosage,initiator concentration,and glass transition temperature to align with industrial practices.Performance evaluation followed updated industry standards,and the emulsion was used to water-based inks for screen printing.This experiment enhances students'awareness of industrial standards,develops their practical engineering skills,and increases their learning motivation.
